I did a ground test over the weekend, and the tests showed that I need a pressure regulator between the nitrous oxide tank. So no tests until I get a proper pressure regulator. No pictures as there is nothing to show right now.

The first few tests took place during the day and not much could be seen, but after dark the exhaust gases could be seen. This first picture is just propane burning without any added oxidizer.

One of the last parts I was working on with the lathe required me to bore out a large internal diameter. This required a spacing disc (read washer) to prevent the tool from damaging itself or the chuck.

I actually do more work than I post. I usually forget to take pictures once I start working with the tools. It also takes me a while to figure out how to make the parts as I am not a qualified machinist. Without further ado more pictures.

I found that I would need a mandrel to finish some of the parts that I have been making. (continue reading…)

This is going to be one of the turbo pumps for the aerospike.

Here I am building an arm to hold the parting tool so I can part off the larger parts.
